SPECIFICATION forming part of Letters Patent No. 716,747, dated December 23, 1902.

Application filed July 25, 1902.

To roZZ whom it may concern.-

Be it known that I, ANNIE OSULLIvAN, a citizen of the United States,.residing at Washington ville, in the county of Orange and State of New York, have invented certain new and useful Improvements in Curtain-Poles, of which the following is a specification.

This invention relates to a pole to be supported in some form of brackets'or sockets for sustaining a curtain or the like, and more particularly to wooden poles, although the invention may be applied with slight modification to a tubular metal pole.

The object of the invention is to provide the pole with a simple and efficient means of securing the curtain to the pole so that it will not slip off or require to be secured by pins or other extraneous means and also to provide such a securing device with self-adjusting means which adapt it to curtains which vary in thickness.

In the accompanying drawings,which serve to illustrate an embodiment of the invention, Figure 1 is a View showing'both ends of a curtain-pole provided with my improvements, the view being on a relatively large scale and partly in vertical axial section. Fig. 2 is a plan of the end of the pole seen at the left in Fig. 1. Fig. 3 is a cross-section of the pole at line a in Fig. 1. Fig. 4. shows the entire pole in its brackets on a small scale.

1 designates the pole, here represented as of wood and cylindrical, with ball ornaments 2 on its ends. This is in itself a commonform of pole.

In order to provide the pole with means for retaining the curtain in place thereon, there is formed in the upper side of the pole and extending practically its entire length a groove 3 to receive a clamping-bar 4, which may be of metal. This bar is hinged to the pole at one end, so that it may be opened out, as seen in Fig. 4, to admit the curtain, and when clamped down, so as to compress the curtain into the groove or channel 8, said bar is fastened securely but detachably to the pole at its other end.

The hinging device is clearly illustrated at the left in Fig. 1 and also in Fig. 2. A hole is bored diametrically into the wooden pole Serial No. 116,903. (n0 model.)

to form a socket for a cylindrical spring-casing 5, and a screw-threaded tang 6 on the inner end of this casing projects through the pole and receives a nut '7. The casing may also have a flange 8 to rest on the upper surface of the pole'and be secured thereto by screws.

In the casing 5 is a plunger 9, having at its lower or inner end a head 10, and about said plunger is a coil-spring 11, embraced between said head and a cap 12,screwed into the casing. The plunger plays through'a hole in the said cap, and its outer end has on it a fork to receive the end of the bar 4, which is coupled by-a hinge-pin 13 to the plunger. At the right-hand end the pole is provided with a device exactlylike that above described, except that for the fixed hinge-pin 13 is substituted a removable securing or locking pin 14.

The clamping-bar 4 is bent at 15 to fit down properly into the groove 3, and it may be providedwith ornamentation P, as seen in Fig. 1, or be left plain, as seen in Fig. 4. This ornamentation does not affect in any way the operativeness of the invention.

It will be understood that where the tang 6 and nut 7 are used the flange 8 is not really necessary to retainthe casing. in place; but both devices may be used. Where an open bracket 16 is employed, as seen in Fig. 3, it may be made to embrace or take under the pole at the point where the casing 5 is situated and the projecting tang and the nut engage the bracket, so as to prevent the pole from turning therein; but where the bracket (as 14 in Fig. 4) embraces the pole exterior to the casing, or between the latter and the end of the pole, the bracket may have means, as a screw 17, to clamp the pole against rotation. 7

Having thus described my invention, I claim- 1. The combination with a curtainpole having aclamping-groove extending along its upper surface for nearly its entire length, and a clamping-bar to clamp the curtain in said groove, said bar having bends near its extremities to free its attaching-studs from said groove, of spring devices secured in the pole at the respective ends of said groove,

detachably securing the bar to the spring device at the other end, substantially as set forth.

In witness whereof I have hereunto signed 15 my name, this 10th days i July, 1902, in the presence of two subscribing witnesses.

the clamping-bar being hinged to one of said spring devices and adapted to be secured detachably to the other.

2. The combination with a curtain pole having in its upper side a longitudinally-extending groove, of the spring devices set in the pole at its respective ends each of said devices comprising a casing, a plunger slid- Witnesses:
